o'rasas.

To all whom it may concern:

Be it known that I, HENRY E. CAMPBELL,

a citizen of the United States, and a resi dent of Bridgewater, in thecounty of Adair and State of Iowa, have invented certain new and usefulImprovements in Barbers- Chair Head-Rests, of which the following is aspecification, reference being had to the accompanying drawings.

This inventionhas relation to certain new i and useful improvements inhead rests for barbers chairs.

The primary object of my invention is to provide a headrest, adapted tobe used in connection with a barbers chairthough the same may alsoibeused in connection with a dentists or like chair, arranged so that thesame can be carried out of working position without detachingthesamefrom the chair;

Another object is to provide a barbers chair with a carrying membergiving pivotal support to the headrest, and constructed so that whensaid head rest is carried'out of its working position, the carryingmemher will be automatically released, permitting the head rest beingcarried below the upper edge of the chair back, without detaching thesame from the chair.

lWith these and other objects in view the present invention consists inthe combination and arrangement of parts as will be hereinafter morefully described and finally pointed out in the appended claims, it beingfurther understood that changes in the specific structure shown anddescribed may be made within-the scope of the claims,without departingfrom the spirit of the invention.

PatentedNom18, 1913. Serial No. 621,753.

A barbers chair as ordinarily constructed includes ahead rest employedonly during the shaving operation. lVhen the customer simply requires ahair cut, the head rest is in. the way of the barber and must beremoved, the rest usually being entirely detached from the chair. In mypresent invention I provide a head rest which while verticallyadjustable can be instantly thrown out of the way when not required,without detaching the same from the chair.

In the accompanying drawings the letter A, designates a'barbers chair ofconventional construction to the back 1, to which is attached a headrest embodying my invention. As shown in Fig. 2, the back 1, of thechair is provided with a middle lengthwise running channel2, the edgesof which are rabbeted or grooved as shown at 3, in Fig. l. The bottom ofthe channel 2, serves as a stop to a runner held therein. This mainchannel 2, near the upper end is further pro vided with a seat 5, whichis continued at right angles to form the stub channel 6, as disclosed inFig. 8. V

Held within the seat 5, is the stem 7, of a spring detent secured bymeans of suitable screws 8. This detent has a lateral extension9,arranged to liewithin the stub channel 6, an upstanding finger piece 10,being continued from the lateral extending portion 9. The portion 9,forms a pawl, the end being held a suitable distance above the bottom ofthe stub channel. In Fig. 6, I have shown the normal position of thisspring detent. As shown, the operating portion 10, is located to theside of the channel 3, upon that side of the chair back.

Slidably held within the main channel 2, is a runner 20, this runnerupon the outer face carrying the flanges 21, as shown in Fig. 9. Thisrunner 20, freely slides within the main channel 2, and upon one sidehas the rack teeth 22, shown in Fig. 10, arranged for co-action with thespring detent 7., which is arranged to lie below and work against therack teeth 22. near the upper end upon the face provided with the rackteeth" 22, is provided with a socket 23, and upon the edge with anopening 24, as clearly disclosed in Fig. 10. Secured to the edge asuitable distance below the opening 24, is an ear 25, this ear pivotallyreceiving the pawl 26, which has an outstanding lip 27, and upon theopposite side is, provided with a guide arm 28, as shown in Fig. 9, theguide arm sliding within a seat 30, below one of the metal flanges 21.This guide arm 28, has an outstanding car 31, limiting the outwardmovement of the pawl, in that this car contacts with a flange- 2 Heldwithin the opening 24, and working against the pawl 26, is a. spring 32,which normally forces the pawl outward in a manner insuring the lip 27,projecting beyond the upper edge of the runner 20. In Fig. 13, I haveshown a detail view of this pawl.

Secured to the lower end of the runner 20, upon one side is a fingerpiece 33, by means of which the runner may be raised. The spring detent7, is normally in engagement with one of the rack teeth 22, of thisrunner and in order to release the detent, the operator presses upon thefinger piece 10, resulting in the detent being carried out of work ingengagement.

Within the outer face of the runner 20, is

a bolt socket 34, shown in Figs. 4 and 9.

V and 12.

Slidably held below the flanges 21, is a plate 36, shown in Fig. 12,from one end of which extends the bolt head 37, as shown in Figs; 4

This bolt head has the upper slanting edge 39, provided with a middlelength wise running groove 40, this groove at its upper end ending in anear socket traversed by a pin 42. The outer face 43, of the bolt headcarries two guide pins 44, which are positioned at the ends of a socket45, as clearly disclosed in Fig. 12. Slidably held to the pins 44, isthe bolt 47 having the outstanding gear 48, the pin receiving slots 49,and the eye 50, as clearly disclosed in Fig.

.11, where a detail of this bolt is shown. It

is within the slot 49, that the pins 44, are slidably held. Theoutwardly directed ear 48, is arranged to work within the socket 45, asdisclosed in Fig. 12. Suitable nuts 51, are secured to the stems 44, toslidably hold the bolt to the bolt head. Held within the socket 45, andagainst the bolt 47, is a spring 53, which at its upper end worksagainst the socket end, while at its lower end this spring rests uponthe ear 48, so that this bolt is held in spring pressed condition,normally being forced outward beyond the base edge of the plate 36, aswill be understood in referring to Fig. 12.

Pivotally held upon the pin 42, is a trip, preferably made of wire,including the striker end 56, held outward of the edge of This runner20, l the bolt head and from which is continued a coil 58, winding aboutthe pin 42, the stem 60, of this trip'being arranged to lie within thegroove 40, with its end engaged within the eye 50, of the bolt 47, asshown. In depressing the projecting end 56, the stemof the trip isthrown outward to actuate the bolt 47. This bolt 47, is arranged forcoaction with the slot 34, within the runner 20.

As shown in Fig. 12, the bolt head 37, is provided with an apertured ear61, while projecting laterally from the bolt head are the trunnions 62,these trunnions being clearly disclosed in Fig. 4. Hingedly con-v nectedto the ear 61, is the bracket 63, this bracket being pivotally held tothe bolt head by means of the pin 64, passing through the ear 61, whileextending from opposite sides of this bracket are the trunnions 65,shown in Fig. 3. Near its upper end this bracket has a pawl slot 66,arranged for coaction with the pawl lip 27. At its uppermost end thebracket 63, carries a block 67, to the edge of which is secured apneumatic tube 68, Having an inflating nozzle 69, as is usual. Thepneumatic tube is secured to the block 67, by means of the fabric 7 O,which is fastened to the block by means of suitable tacks or screws 71.his member 67, in connection with the pneumatic tube, forms the 9 headrest proper of my invention and is of a shape adapted to convenientlyreceive the back of a human head. Secured to the trunnions 62, and 65,is a spring including two similar arms 73, and 74, having an inter-.mediately positioned spring coil 75. The arms end in the eyes 7 6, theeye of the arm- 73, being arranged to be securedto the trunnion 62,while the eye of the opposite arm 74, is arranged to be brought intoengagement with the bracket trunnion 65, so that the bracket 63, isnormally thrown in a direction insuring the bracket being held in aspring pressed condition against the back of the chair. There are twosuch springs employed to force the bracket upward. As shown in Fig. 12,the end 56, of the trip is in the path of the lower beveled end of thebracket so that when this bracket is released from the runner and iscarried rearwardly, it will engage the trip end 56, to actuate the tripto release the bolt 47, from its socket 34, so that the plate 36, andconnected bolt head will drop to the bottom of the runner, being stoppedagainst the finger piece 33. In this position, as is shown in Fig. 14,the head rest will be held below the upper edge of the chair back andentirely out of the way of the operator.

The runner 20, is held in its channel by means of the face 3.

The operation of my device is very simple. The runner 20, is firstinserted into the channel 2, of the chair back so that the same isstopped against the bottom thereof. In this position the spring detent7, will be just above the uppermost rack tooth 22. The bolt plate 36, isnext inserted and slid downward until the bolt 47, finds a seat withinthe socket 34. In this position the upper end of the bracket 63, willrest upon the upper end of the runner, as clearly disclosed in Fig. 3.In this position the pawl 26, is in engagement with the bracket to holdthe same to the runner. upward and given proper adjustment. Should itthen be desired. to throw the head rest out of working position, theoperator simply depresses the pawl 26, so that the same will ride freeof the bracket socket and carry this bracket 63, backward. In doing thisthe bracket automatically trips the bolt 47, carrying the same out ofthe slot 84:, so that the head rest can be dropped below the upper edgeof the chair. The runner can then also be lowered.

A head rest constructed according to my invention is simple andinexpensive in construction and both durable and eificient in operation,and the adjustments can be made with ease and accuracy. An incident ofconvenience to this arrangement of head rests for barbers and otherchairs, is that the same can be instantly thrown to the rear of andbelow the upper edge of the chair back without detaching the head restfrom the chair.
